To whom'it'may concern:

Beat knownthat I SIMEON S. JACKSON, a snb ect of Great Britain, residing at Boston, inthe county of Suffolk, State of Massar chuset h a ve invented a certain new and useful provement in Weft-Re lenishing Mechanism for Looms, of which t e followinglis'p specification, reference being had to the accompanying drawings. The invention is an improvement in loom weft-replenishing mechanism of the class efcop-spindles, or the like) placed in the feed- "ers or magazines; and also has relation to the features of construction of the said supports providing for mounting the said springs in connection with such supports.

The invention provides a filling-carrier engaging and retaining spring having an improved action and also less liability to breakage than springs which have been employed heretofore in certain instances; and

also rovides a filling-carrier support of a nove construction especially adapted for the em loym'ent of springs of the said form, an for, the ready and convenient application and removal of such springs.

The features of the invention may be employed at either or both ends of the fillingcarrier. They are illustrated in the draw ings as embodied in the tip-supporting means of a rotary feeder or magazine.

In the drawings, Fig. 1 shows, part1 with the projectmg plate. adjacent the broken away, a rotar feeder or magazine embodying the said eatures.

'Fig. 2 1s a back view of the t1p-support of the feeder or magazine of Fig. 1, shown separately; and Fig. 3 is a view thereof 1n vertical section in the plane of line 3, 3, ofFig.2.

Fig. 4 is a face VIEW ofthe spring-engaging ring which is a portion of the said tip-support, showing the recurved tails of the tip-springs, with thesprings 1n vert1cal section in the plane of line 4. 4; Fig.3.

in vertical section, ange. of the framebutt-support partly Fig. 5 is a face view on an enlarged scale of the tip-engaging portion of a s ring; Fig. 6 is an edge view thereof; and ig. 7 is a view in longitudinal section on line 7, 7 of Fig. 5.

Fig. 1 shows the main portion of the stand 1 of a rotary feeder or magazine ofordinary type, and shows also the spindle 2 projecting horizontally from the upright portion of the said stand and serving for the support of ,the rotary portion of the feeder or magazine. 3 is the wheel or late formin the support for the butts of t 1e reserve fi lingcarriers lwhich are placed in the feeder or magazine. Fig. 1 shows onlya portion of the width of the flange, of the said upright portion of the stand. which projects over the periphery of wheel 3 and keeps the filling-carr1er butts within the butt-pockets 3, 3, that are formed in the said eriphery. 5 is the elongated hub or sleeve of the buttsupport, said hub or sleeve fitting upon the said spindle 2. 6 is the ratchet-wheel upon the inner face of the butt-support, the teeth of which in practice are engaged by the devices (not shown) for rotatin the feeder or magazine forwardly and loc ring it from backward rotation. 7 is the wheel or plate of the tip-support, mounted by means of its hub 8 upon a reduced prolongation of the hub or sleeve 5 of the butt-support, and secured thereon by means of clamping screws 9 at the proper'distance from the wheel or plate of the butt-support. At 10 is the filling-end su )port, also mounted upon the prolongation o hub or sleeve 5, and fastened thereon b clamping screw 11. 12 is the filling-end older projecting from the filling-end support 10, and upon which are wrapped the free extremities of the fillingends that are extended from the fillin -car ries outward around the edge of the fi lingend support.

lVith the exception of-the tip-support, the parts thus far mentioned are not involved directly in theinvention, and may or. iate-t ofthe tip-suppprt preferably is made with a continuous rim or periphery.

As usual, the said wheel or plate is formed with a circular series of holes 7, 7 through .its marginal portion, but inside the said 45' of theQillustrated embodiment.

stea plate continuous, rim or perpliery, such holes const-ituting poekets for the accommodation of the tips of the filling-carriers 4 that are applied to the feeder or magazine as in Fig.

5 1. The carrierengaging ends a, a, of the tipsprings enter into the empty pockets as in 3.. its-heretofore, the said ends a are inclinedbackwardly as in Figs. 1, 3, 6

and 7, so that when the attendant upon the- 10 loom with which the feeder or magazine is -,*"conn'ectejd pushes the tip'of a filling-carrier inward radially into a pocket the pressure ofsaid' tip'against the inclined surface of the" corresponding spring-end a will defleetsuch spring-end backward, permitting 'the'carrier-tip to pass inward by the pro.

W feeder'ormagazine to the shuttle of the loom.

' "'Inpractice, tip-springs break as a result of ",7 frequently being bent, or of being subjected {to undue-strains in the operation of placing 'filling-carriersin the feeder or magazine, or

because of the-sudden and severe action when afilling-carrier is transferred to the sliuttlefior as a result of various accidents.

. Thereupon, replacement is unnecessary.

" The 3 improved filling-carrier engaging "rid retainingspring which is one feature of'the invention issubstantially hair-pin sliapedtY-"lt is made of a strip of fiat springif' material of considerable length, doubled or reejurved upon itself so as to form the two a'rinsorbranchesa, a? of a U. The relative 1' length of the two arms or branches with respect-to eachother may vary. Usually, the

- econdary arm, branch, or tail a? is shorter 5 than the main arm or branch (1, as in the case The spring itli'usiformed is applied to the back of the d An annular shoulder 7 Vorixthe saidwheel or plate, and with which -.."th'e.-bend of the spring makes contact, serves a-s-"astopto-fix the distance of said bend frojm theaxis of the feeder or magazine.

'J'T'he spring is intended to react, when the carrier-engaging arm is pressed backward,

in virtue of engagement of the recurved arm or tail with atconvenient abutment. Preferably, the bend of the spring is wide and ."rcurndedras the drawing, to lessen the liability to cracking and breakage at the Qgbend as a result of the flexing of the spring in, use. In practice, the proportions and precise form of the spring may vary. as

Yell as the location of the abutment and iiwith and reacts from the latter. In the fi 5' illustrated embodiment the secondary arm,

he -manner in which the spring engages.

branch, or tail a is -turned backward and outward away-from the main orengaging arm or branch or, and bears by its outturned. face against an abutmentconstitutedby the inner surface of a ring, I), {at the back of the wheel or plate Y 7 Consequently, the spring reacts from the said surface of the said ring in a manne which causes its arm or branch m' topress against the back or outer surface of the wheel or plate 7, and tends to hold the engaging enduo'fwsaid arm or branch in the correspondingpo'cket 7 and in engagement withthe-filling carrie-r tip as in Fig. 1 when the-filling-carrier is in place. It will be obvious that when-the arm a. is bent backward by the :ac-tion' of the filling-carrier tip against: the .engagingend of such arm, as .thenfillin'g-"c'arrier is inserted into or driven from the pocketfifit, the bending of thespring isdistributedover a total length Very much greater-1than{that of the shorter straight springs, rigidly clipped and held at their inner ends, heretofore in use.

F or convenience in construction.,.1=ing,fi'

in the present instance ismade as asepagrate piece and attached by fasteningsnbfto he outer face'of wheel or plate 7., s i

The manner and means ofholding he springs in working relations with, the other parts will vary in practice, accordin to the specific character of the ;.constructi f adopted. As one feature, of the invent on, the ring I) is shown.p'roi'ided= vitlra ioyerhanging lip 6 projecting slig li tly t wheel or plate 7. This lip,by fengagemeht with the extremity of theitailof asprm'g prevents outward radialmovement Qof, the spring. T he tendency of, the tailto' spread away from arm a keeps saidexti'emity position to engage with the lip; Thesprings are shown as spacedapart from-one another, and. prevented from displacement-.sidewise, substantially as heretofore. namely byfreason of their engaging endsbeingentered into the pockets 7* of wheel or plate 7, andfby means of lugs or projections,-.15, 15, interjvening between their inner portions. In the present instance the said lugs or, projections are formed upon ring I) andenter bet-ween the tails of adjoining sp ings.

In order to facilitatethe operation of removing a spring when necessary, holesfbf, b are made through ing I), one for ever; spring in this instance. By pushing a suitable implement through one of these holes,

the corresponding spring-tail a? may be pressed away from under the lip b* ,"and if at the same time the end of the long armbranch. of the spring is pressed inward vthrough the pocket 7 which itoccup'ies, so

as thereby to be pushedinwardcl'earofthc overhanging portion ofthe rimfiof wheeler plate 7, the. spring will be free to be drawn endwise outward far enough to clear its bent or bowed portion from ring I). T hen, after tilting the spring so as to turn the said bent or bowed portion away from the rinp the else by directly pushing it bent end first into such space, until the spring-tail springs past which will lock such spring in working position. Shoulder 7" of wheel or plate T will prevent'the spring "rom occupying a position too far inward toward .the center of the feeder or magazine.

The manner and means of combining ring b'with wheel or plate 7 may vary in practice. It is shown as permanently fastened to said wheel or plate by rivets. but it may be attached removably thereto through the employment of other attaching means. Permanent types of fastening-means are satisfactory when the general construction provides what may be termed free springs; i. e., when the springs are capable of being applied, held in position, and removed, without the use of bolts and the like.

What is claimed as the invention 1. In combination a filling-carrier engaging spring of U shape, comprising a branch or arm which serves as a reaction-member and a second branch or arm constructed to engage and retain a filling-carrier, and a filling-carrier supporting member having, a shoulder with which the bend of the spring contacts, a wall serving as a I'Lut'tlOll-llblltment, and means to prevent displacement of the spring radially outward.

2. In a feeder or magaz ne for filling-carand under the lip I)".

riers, in combination, a idling-carrie. supporting member having spaced-apart walls, one of them rovided with a shoulder and a U-shaped lillingwarrier engaging spring having it bend mnlined between the said walls, with one of its arms or branches cngaged with said shoulder so that thereby the spring is held from radial displacement.

3. In a feeder or magazine for filling-can riers, in combination a U shaped fillingcarrier engaging spring. and a filling-carrier supporting; member having spaced-apart walls between which said spring: is entered. one of the said walls provided with a shoulder with which one arm or branch of the spring engages to hold the sprinp in place, and also formed with an opening through which such arm or branch may be reached to push it-out of engagement with said shoulder, to free the spring for removal.

t. In a feeder or magazine for filling-can riers, in combination, a U shaped filling-carrier engaging spring, and a filling-carrier supporting member having spaced-apart walls between which said spring is entered, a shoulder with which the bend of the spring engages so as to limit movement of the spring endwise in one direction and a shoulder with which one arm or branch of the spring engages to hold the spring from movement endwise in the other direction.

In testimony whereof l allix my signature in presence of two witnesses.
